Photovoltaic module clip
A photovoltaic (PV) module clip, and methods of fastening a PV module to a structural member using the PV module clip, are described. In an example, a PV module clip includes a toe portion interconnected with several legs by a neck portion. The toe portion may be inserted through several aligned holes of a PV module frame and a mounting assembly strut to an underside of the strut. The neck portion may extend upward from the toe portion through the aligned holes to the legs above the strut. The legs may extend around a portion of the strut in a tensioned state, and engage with a retaining feature to hold the legs in the tensioned state. Accordingly, the legs may clamp the PV module to the mounting assembly.
1. A photovoltaic (PV) module assembly, comprising:
a mounting assembly having a strut, wherein the strut includes a mounting wall having an upper surface, and a sidewall, and wherein a strut toe opening extends through the mounting wall;
a PV module having a PV laminate mounted on a PV frame, wherein the PV frame includes a frame flange mounted on the upper surface of the strut, wherein a flange toe opening extends through the frame flange, and wherein the strut toe opening and the flange toe opening are aligned along an axis; and
a PV module clip including
a toe portion having an upper toe surface extending along a lateral plane below the mounting wall,
one or more neck portions extending from the toe portion through the strut toe opening and the flange toe opening, and
a plurality of legs, wherein each leg is coupled to a respective neck portion at a distal leg junction, and wherein each leg extends laterally outward from the distal leg junction to a proximal leg junction at the sidewall.
2. The PV module assembly of claim 1 , wherein each leg extends parallel to the upper surface of the strut from the distal leg junction to a knee portion, and wherein each leg extends parallel to the sidewall from the knee portion to the proximal leg junction.
3. The PV module assembly of claim 1 , wherein the PV module clip further includes a plurality of retaining portions, wherein each retaining portion includes a hook-shaped portion extending from the proximal leg junction to a clip end between the sidewall and a vertical plane containing the axis.
4. The PV module assembly of claim 3 , wherein the strut further includes a retaining opening extending through the sidewall, and wherein one of the retaining portions extends laterally inward from a respective one of the proximal leg junctions through the retaining opening.
5. The PV module assembly of claim 4 , wherein the retaining opening includes an L-shaped slot.
6. The PV module assembly of claim 3 , wherein the hook-shaped portion includes a bend surface, wherein the sidewall includes a bottom edge, and wherein the bend surface is retained at the bottom edge of the sidewall.
7. A solar-tracking photovoltaic (PV) system, comprising:
a torque tube extending along a longitudinal axis and pivotable about the longitudinal axis;
a mounting assembly having a strut, wherein the strut includes a mounting wall having an upper surface, and a sidewall, and wherein a strut toe opening extends through the mounting wall;
a PV module having a PV laminate mounted on a PV frame, wherein the PV frame includes a frame flange mounted on the upper surface of the strut, wherein a flange toe opening extends through the frame flange, and wherein the strut toe opening and the flange toe opening are aligned along an axis; and
a PV module clip including
a toe portion having an upper toe surface extending along a lateral plane below the mounting wall,
one or more neck portions extending from the toe portion through the strut toe opening and the flange toe opening, and
a plurality of legs, wherein each leg is coupled to a respective neck portion at a distal leg junction, and wherein each leg extends laterally outward from the distal leg junction to a proximal leg junction at the sidewall.
8. The solar-tracking PV system of claim 7 , wherein each leg extends parallel to the upper surface from the distal leg junction to a knee portion, and wherein each leg extends parallel to the sidewall from the knee portion to the proximal leg junction.
9. The solar-tracking PV system of claim 7 , wherein the PV module clip further includes a plurality of retaining portions, wherein each retaining portion includes a hook-shaped portion extending from the proximal leg junction to a clip end between the sidewall and a vertical plane containing the axis.
10. The solar-tracking PV system of claim 9 , wherein the strut further includes a retaining opening extending through the sidewall, and wherein one of the retaining portions extends laterally inward from a respective one of the proximal leg junctions through the retaining opening.
11. The solar-tracking PV system of claim 10 , wherein the retaining opening includes an L-shaped slot.
